Title: Cleaning of sea area by artificial coal ash zeolite
Inventor: SHIMOGAKI HISASHI
IPC: B01J20/18
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To use a coal ash, which is an industrial waste, effectively and to prevent eutrophication by nutritious salts and gas in a closed sea area such as a bay and the deterioration of water quality associated with the eutrophication by placing artificial zeolite obtained by the hydrothermal chemical treatment of coal ash on the upper surface of a bottom earth layer in the sea area. SOLUTION: An artificial zeolite 10 obtained by the hydrothermal chemical treatment of coal ash is placed on the upper part surface of a bottom earth layer 20 in a closed sea area S such as a bay. In this way, coal ash, which is industrial waste, is used effectively, and the deterioration of water quality by the eutrophication etc., of the sea area S is prevented. The artificial zeolite 10 is obtained from a powdery material from which impurity NaOH was removed by a process in which for example, coal ash (fly ash) was heat-treated in a NaOH solution, and the product was washed with water. Phillipsite and faujasite, which are zeolite minerals, are formed on the surface to give a gas- barrier performance and a cation exchange capacity comparable to those of natural zeolite.

Abstract: PURPOSE:To offer a transistor which can comply with a high speed and a large-scale integration of an LSI by a method wherein a collector contact region is formed in the center, a base contact region is formed at its outside and an emitter is formed at an outermost circumference. CONSTITUTION:A slender and long emitter region 31 which is required to lower a base resistance and to increase a cutoff frequency is obtained when it is formed at an outer circumference of an element formation region; it can be formed as the smallest element area. A base contact region 32 is formed at the inside of the emitter region 31; a collector contact region 33 which is connected only to a buried layer 2 to be used as a collector and which does not require an area specially is formed in the central part at its inside. Sizes of the individual regions differ largely; the outside region is longer and the area becomes larger; as compared with transistors of a structure in which an emitter is formed in the center, an emitter area becomes large by 8.9 times or 4.0 times; it is possible to solve a problem of a drop in a cutoff frequency in a large electric-current region due to an increase in a current density.

Title: Lighting device for discharge lamp
Inventor: NAGASE HARUO
IPC: H05B41/24
Filed: 1990-08-11
Abstract: PURPOSE:To ensure the restarting of a high pressure discharge lamp and the lighting device of the lamp small and light by setting the generation period of an intermittent high frequency voltage generated from a control means at the restarting time of the lamp longer than that at the no-load time, so as to elevate the generated high frequency voltage to a voltage able to restart the lamp. CONSTITUTION:When a transistor Q3 is turned off by unlighting of a high pressure discharge lamp, the charge in a capacitor C4 is discharged through a positive characteristic thermistor RT. The thermistor RT is placed at a position where the temperature is kept high during the lighting of the lamp, and so the resistance of the thermistor is kept high during the lighting, therefore the discharge duration of the capacitor C4 becomes long to elongate the no- output period of an oscillation circuit 9. thereby the continuous temperature rise of the luminous tube due to repeated slight discharges during the restarting can be eliminated to restart the lamp reliably, and the need to increase the output of the generating circuit of the high pressure discharge lamp voltage can be eliminated to make the device small and light.
